Answer:
1)y=2x-1: Neither
2)y=-2+5: Parallel
3)y=12x+7: Perpendicular
Step-by-step explanation:
I went on Desmos.com and graphed all of the equations. 1) crosses the equation but is not perpendicular because it doesnt form a 90 degree angle. 2) is obvious when you look at the graph and lastly 3) is the only one left and when it crosses it makes a 90 degree angle. Hope this helps <3
